Assessment of Satellite Aerosol Optical Depth to Estimate Particulate Matter Distribution in Valencia City

Year: 2018

Type: conference-paper

Abstract: The estimation of exposure to PM10and PM2.5requires the knowledge of surface concentration at high temporal and spatial resolutions. In this paper, the relation between PM10and PM2.5ground data and MODIS AOD satellite data has been evaluated to determine the concentration of particulate matter in Valencia, Spain. This was done using data from the Valencian Network of Surveillance and Control of Air Pollution and the scientific data set “Optical Depth Land and Ocean” from MODIS Terra and Aqua with 3km of spatial resolution. The linear regression model for PM10provided a regression slope of 25.99 μg.m-3and an interception of 12.07 μg.m-3(RMSE=8.61 μg.m-3), while for PM2.5the slope and interception were 26.87 μg.m-3and 5.98 μg.m-3(RMSE=5.5 μg.m-3).
